Standard octave-band smoothing hides the fine structure of comb-filter patterns.

Evidence

Only very high-resolution measurements would reveal these details, normal 1/3- or 1/6-octave band curve smoothing would reveal none of this detail. What would typically be seen would be a single line that might suggest the first undulations at the low end of the frequency scale, gradually showing an inability to reveal the full depth of the dips, and from some frequency upwards simply reverting to a straight horizontal line following the top of the black area. — Toole, Floyd E, Sound reproduction- the acoustics and…, 664
